A structural joint includes inner preforms 20, 22 and outer preforms 24, 26 of material. The outer preform has legs 38, 40 that extend longitudinally and laterally from a fold 42. The inner preforms project longitudinally past the fold to define a spar 44. A wing, such as wings 50, 52, 54, 56, exte
A structural joint includes inner preforms 20, 22 and outer preforms 24, 26 of material. The outer preform has legs 38, 40 that extend longitudinally and laterally from a fold 42. The inner preforms project longitudinally past the fold to define a spar 44. A wing, such as wings 50, 52, 54, 56, extends from the spar. The spar and wing cooperate with a substructure to resist separation of the spar and wing from the substructure. The joint is described in the context of a duct, such as a turbine engine inlet duct, but may be used in other applications.

We claim: 1. A joint comprising: an outer preform having legs extending longitudinally and laterally from a fold in the outer preform, an inner preform projecting longitudinally past the fold to define a spar, the spar including a wing angularly offset from the spar; and a substructure cooperating
We claim: 1. A joint comprising: an outer preform having legs extending longitudinally and laterally from a fold in the outer preform, an inner preform projecting longitudinally past the fold to define a spar, the spar including a wing angularly offset from the spar; and a substructure cooperating with the spar and wing to resist separation of spar and wing from the substructure. 2. The joint of claim 1 wherein: the substructure includes a forward ring, an aft ring and an insert; the spar includes a pair of forward wings extending in laterally opposite directions from each other and a pair of aft wings also extending in laterally opposite directions from each other; and the forward wings nest between the forward ring and the insert and the aft wings nest between the aft ring and the insert. 3. The joint of claim 1 wherein a cover preform covers the laterally extending leg of the outer preform. 4. The joint of claim 1 comprising an intermediate preform residing between the inner and outer preforms and projecting longitudinally past the fold to cooperate with the inner preform in defining the spar. 5. The joint of claim 4 wherein the projecting portion of the intermediate preform is devoid of any wings. 6. The joint claim 1 wherein the wing is angularly offset from the spar by about 90 degrees. 7. The joint of claim 1 wherein the spar and wing meet at a crease, and the inner preform comprises a fabric with fibers oriented off-angle relative to the crease. 8. A duct comprising a longitudinally extending strut comprised of an inner preform and an outer preform, the outer preform having legs extending longitudinally and laterally from a fold in the outer preform so that the laterally extending legs form at least a portion of a duct wall, the inner preform projecting longitudinally past the fold to define a spar, the spar including a wing angularly offset from the spar. 9. The duct of claim 8 comprising a substructure cooperating with the spar and wing to resist separation of the strut from the substructure. 10. The duct of claim 9 wherein: the substructure includes a forward ring, an aft ring and an insert; the spar includes a pair of forward wings extending in laterally opposite directions from each other and a pair of aft wings also extending in laterally opposite directions from each other; and the forward wings nest between the forward ring and the insert and the aft wings nest between the aft ring and the insert. 11. The duct of claim 8 wherein a cover preform covers the laterally extending leg of the outer preform. 12. The duct of claim 8 comprising an intermediate preform residing between the inner and outer preforms and projecting longitudinally past the fold to cooperate with the inner preform in defining the spar. 13. The duct of claim 12 wherein the projecting portion of the intermediate preform is devoid of any wings. 14. The duct of claim 8 wherein the fold extends in a substantially axial direction. 15. The duct of claim 8 wherein the wing is angularly offset from the spar by about 90 degrees. 16. The duct of claim 8 wherein the duct circumscribes a centerline, the longitudinal direction is radial and the lateral direction is circumferential. 17. The duct of claim 8 wherein the spar and wing meet at a crease, and the inner preform comprises a fabric with fibers oriented off-angle relative to the crease. 18. The duct of claim 8 wherein the wing extends laterally toward a companion wing associated with a neighboring strut. 19. The duct of claim 18 wherein the wing abuts the companion wing. 20. The duct of claim 19 wherein the wing overlaps the companion wing. 21. An inlet case, comprising: radially extending struts each comprised of at least an inner preform and an outer preform, the outer preform of each strut having legs extending radially and circumferentially from a fold in the outer preform to define, at least in part, a case wall, the inner preform projecting radially past the fold to define a spar, the spar including a pair of circumferentially extending forward wings and a pair of circumferentially extending aft wings; inserts located circumferentially between neighboring spars, and axially between a forward wing and a counterpart aft wing; a forward ring axially forward of the forward wings; an aft ring axially aft of the aft wings; and a cover covering the circumferentially extending leg of the outer preform and cooperating therewith in defining the case wall, the cover also extending over a face of the forward ring.
